    Position tolerance datums

    Hi Alex, Sorry but have been busy last week. It's a single part with two bushings. Bushing as slightly larger diameter to account for variation in position and diameter tolerances.

    Position tolerance datums

    Hello both, Yes the original question has been asnwered :) Only way to produce enough information is to produce all information which I can't since it's sensitive business information. I ahve simplified it to get an answer to my "basic" question. What prompted me to ask the question is that I...

    Position tolerance datums

    Burunduk, Rigth now there is no such division of roles. This I have thought about in the past but we are working with existing parts which are not possible to change now (we would lose compatability with older versions). Also I think we have enough margin (the bushing is slightly larger then...

    Position tolerance datums

    Hey! Using ISO yes. I have to check then what is the difference there. Replying to both there are floating features that prevent an over-constrained situation.

    Position tolerance datums

    Ah, outer shape is also important to control but I also agree with jassco that profiles can be used there in realtion to the hole features. Thanks again!

    Position tolerance datums

    Hello all again, First thanks a lot for the discussion and ideas! I think by trying to simplify the part and its function (also can't share full design obviouslly) maybe left too much open. The assembly condition is more of less like Burunduk refers. The two 9 mm holes have pins presse in and...

    Position tolerance datums

    Hello all, Thanks for the answers. The sketch is just a simplification of the actual part. Both the relative location of the holes and it's position to the outer shape are important. THe reason why I want the 11 mm hole controlled in relation to the 9 mm one is that when assembled the 9 mm hole...

    Position tolerance datums

    Hello all, I have been trying to find an answer to this one and maybe you could give me your 2 cents. If I want to control the position of one hole in relation to another do you considered that I still need the 3 datums? Below I made a simplified drawing of what I consider to be a correct...
